I'm not comparing branding to the holocaust. I'm talking about people's tolerance of things. It was an example, NOT a comparison. You said "Why is it that people feel the need to force thier "morals" onto other people". And I was simply explainging why it's often the case where we should show objection, and not just be lovely and tolerant.
Brands can be altered quite easily, all you have to do is place another brand over it or cut about at the horse's skin. Just becuase branding is more efficient, does not mean it's better for the horse.
From Horse and Hound
"In terms of pain and local inflammation, hot branding
proved to be more painful and caused greater prolonged sensitivity in the skin than microchipping
There was more swelling and more evidence of skin damage in branding than in microchipping
, which is not surprising and has led the authors to call for branding to be abandoned wherever possible."
EDIT: I'm also adding that microchipping is more common in the UK than in America. So maybe it makes less sense over in America to microchip. But the OP wants to get branding banned in Scotland, and seen as microchipping is compulsory for every foal nowadays, there is no doubt that there is plenty technology to identify horses over there and no point in the continuation of branding. Also the OP is a vet, so I'm pretty sure she knows what she's doing
